^ Application filed June 7. 1882. (No model.)

VTo allebhom 'tt .muy concern i Be itkuow-n .that-I, HENRY GOKER, of Inl dianapolis, in'the county of 1Marion and State of Indiana, have invented a new and useful vThis invention relates to conveyors used in bnildingsor'storin'g grain, for conveying grain lin bulkor largequautities from one .part of the building to another. The conveyers ingordithree kinds-namelhthe diag-belt con veyer, I the worm or screw conveyer,rand the iiight-con-` `veyer,ral'1 otfwhi'ch as heretofore constructed are more 'or less defective, especially in their entlkinds of grain together. Particularly is 4this the case with the sorewor worm conveyor, and whenever occurring it is a serious source of 'hin deranceyanrnoyance, .and not infrequently y l lgreat inancialloss. My invention, which ref ila-tes to the flight .type of' conveyer, not only 'removes this diiiicuity, but possess-es other -adi suit circumstances. Fi g. 2 is avertical longitudinal section through one of the troughs. Fig. 3 is a perspective View in part, mainlyiu holeot' either trough, and of a gate for opening and closing said dump-hole and device-s for operating said gate. Fig. 4 is a View in perspective of the dumpfhole frame, and Fig. 5 a transverse section ot' said frame. is an end elevation, in part, of the tit'ofconvey` ers; and Figs. 7 and 8a pla'and longitudinal used in each conveyor, with 'a flight attached; and Fig. 9, transverse ,Sections through the links of the chain ou the lines w te and z z in 1n 'thedrawings, A' Aindicate two conveyor boxes or troughs, each of whieh,when the construction of the house yor building will'adrnit oi' it., may be 4rn-ade to' grade downward in the direction in which the grain is required 'to move, for the purpose of `more easily conveying'the-grain, as shown in Fig. 2, thearroww indicati ug the direction in .inotion of the iiights vantages, including increased durability and eiiectiveness, together with diminution of friction; an'd'iteonzsis-ts in a novel .construction of parts whereby :a more perfect dum pho-le than is usual with other trough and flight convey- Aers is obtained, the iiights move with more-per- :Feet Vfreedom through the .trough .and are :pre- V vented fronrcarrying4 grain over the 'dn-Inphol-:e or lits edges, and the `ilfinlrs .ot' the chain by which the iii-gh'ts are carried and moved are prevented from :hol-ding grain while passv. irrgiover the dump-hole.

Reference is 'to be had yto the accompanying drawings, forming p21-nt of this specification in which similar ietterso'f reference indicate corresponding parts Vin all the iigures.`

iexitension'froin one end 'of` the :house v.tio they other, the lights wh ich travelthrongh theone trough moving 'iin a .reverse `direc-tion to that of the 'flights in thearijacent trough, and both 'troughs slightly inclining Y.do-vi'nward' in the directions in which their respective ights'y travel; but this .particulararrangementof the 1-itrfonghs and dip' of them forms no part of this;

Wh en side a sufficient space should Lbe left between i 'themfor the usual weigh-hopper turn-head to spout-into either; but, if preferrerhsaidtrouglhs admit of the saine. in such'arrangement the downgrades of the'troughs in the directions in which their respective flights move through them facilitate the transfer ofthe grain,-save power, and reduce wear and tear. Gates lare provided'at any poiutalong .either trough for house at the will of the weigh-master. These .sect-ion, respectively, of a portion ofthe chain the discharge ofthe gra-in into any part of the' invention, and the same may be changed to .4

B B are the endless chains, to every fourth Aor more or less distant linkof which the flights (l lG that lcarry the grain along the "troughs, are attached, said chains passing at the ends..

and transverse bars having apertures'b bin between them, and arranged so that the upper surface of said frame, within either.. trough, is flush with the bottom d of the trough, and the discharge-apertures b b occupy va diagonal or oblique position across the tro ugh, and when not closed by the gate F present a sufcient area for the free discharge of the grain through them, notwithstanding that the grain is conveyed through the trough inflarge quantities and at a high rat-e of speed. Said frame E may be planed onits upper surfaceto make it line even with the bottom d of the trough, and its cross-bars'also be planed on their sides to provide for a perfect and parallel lit of prongs accordingly as the gate is slid in or out in direction of the prongs, open or close thedischarge-apertures b b.

Either gate F may be vmade o't hard wood clamped together by bolts, and with its prongs or tongues e c made to form a close but free fit betweenithe cross-bars of th'eframe E, which may be o f metal. When closed said tongues c c are ush with theupper surfaces of the cross-bars of said frame E and with the bottom d of the trough. Said gate F may be opened and closedthat is, its tongued portion slid in or out of the trough diagonally-by means of a rack, f, pinion g, and sprocketwheel h, actuated by a pendent chain..

Bythe diagonal position of thedump-holes or apertures b b relatively tothelengthof the troughs the i ghts C O, when traveling through the troughs, are restrained from'catching against the edges of or falling into saidv holes, which would break them, and whichgthey wouldbe sure to do it' said liolesranl straight across the troughs.

The bottomd of either trough-,excepting where it is intercepted by the grate-like frame E, is made of a cast plate or plates of glass, which, from its smoothness, prevents undue friction, and by its hardness resists wear, thereby not 4merely adding to the durability ot' the trough, but doing away with that unevenness ot' Wear which takes place when the bottom is made of wood and causes gutters or furrows to be cut in it, which gutters in timei become pockets, that collect the grain and leadto the mixing ot' it, and to remove such gut.

ters by planing the'bottom from 1time to time is a serious interruption. Even if the bottoms of the troughs be made of the hardest wood,

'the grit and grain passing, over them will not.

fail to cut or groove them, whereas when said bottoms vare made ot' glass or other vitreous material their durability is permanent, sotfar as wear is concerned, va great saving ot' power' is el'ected by the diminution of friction inthe grain and vfiights passing over them, and inixing o'ithe grain is prevented. .r y y The ights GG, which may be of malleable iron, are of flat plate-like construction,`slightly ydiminishing in thickness fromy their centers, and. of the same width, or nearly so, as the trough in which. they travel.

Either'chain B is composed of a series of open oblong links having .sides t' i, united at their one end by a cross-round, k, and terminating. at their opposite end in hooks ll, eonnected by ahalf or partial rounded cross-socket, m, within which and the hooks l Zthe cross-round la of the adjacent linklies to form the. connection between the links, certain `of which have lthe flights arranged on them by the passage ot' a' link through each flight, and sol that it projects alikeon vopposite sides oi' the Hight.' This construction' ot' the links, which are rounded on their sides andhave knife-edges, as shown in Fig. 9, leaves no room-for grain to lodge on them while passing overth'e dumphole, thereby aiding in doingaway'with the'mixing of th grain, and theV trough is swept by the ilights perfectly clean as soon as the supply of l grain is cut off. The dump-,apertures bb being oblique to the lline of vmotion of the flights over them, said ilights will gradually but surely pass-'all the grain in front of them' through saidapertures, and none will be carried over. to occasion mixing, as hereinbefore ICO IIS

have their greatest strength at their jaw or hook;ends,and,are o f proportionate strength throughout, and theiry construction, including theirknite-edge formations on both sides,pre

' vents 'thelodgnient of the smallest grain while f passing over ,the dump-hole. ,The construction and shape ofthe'iiights also contribute to' give`- like security and strength, no pockets being I' Y left iorv the 'lodgment of grain, but theigb'ts making a close litl overthe links by constructing the nights with holes inA them to receive the links through their centers and riveting .them to projecting 'ears i? of across-bar, i',

which unites the opposite sides of the links to .which the flights are attached, as shown in Figs. 7 and8, and closes'or lls the holes in theights, through which the ends and crossbars kof the said links arepassed. ,s It will engage with one another, so that they will not become-,detached either when moving in a straight line or when passing round the wheels.

5 at the ends ofthe chains, in Which'are gaps for the reception of the ights. Having thus fully described my invention, I

claim as new and desire to secure by Letters Patent- 1. In a trough andflight conveyor for conveying grain, the trough provided Withva series of dumping-apertures aran ged diagonally or oblique to said trough and tothe line of motion of the iiights passing therethrough, sub- ;stafntially as specified. y j .2.
